Unfortunately, prison is a class in master crime, mayhem. No one in prison for 20 years should ever be let out. I am a big proponent of building a city with free food, housing, jobs responsibility ,,,, and throw in free drugs. Those that test negative for 5 years can come out, all others will OD in short order. Used crappy drugs as standard and good drugs as currency to get things done right. Everyone going in agrees that violent crime can and will be met with immediate death via fence guards. They get the choice - live in their free drug utopia (with signed away rights) or stay in prison. The other aspect is people can freely enter drugtopia after signing rights away and waiting 21 days. No one under 25 allowed.
Sounds like the plot of “Brave New World”...................
